A 4 channel WiFi + RF 433MHz controller with voltage free outputs compatible with Tuya, Smart Life software and with all its capabilities.
The main purpose of the module is to add intelligence to the devices you already have. The small size and the power supply voltage range of 5 to 32V AC make it easy to install in target devices such as garage doors, gate controllers, motor controllers, heating cookers, roller shutters, garden irrigation systems.
The controller can operate in one of three modes:
- Normal - i.e. each relay can be independently switched on and off
- Link (interlock) - this function causes that only one of the four relays may be switched on at a time, switching on one relay automatically switches off the other, a function used in control of roller blinds and motors. Enabling this function automatically disables the impulse control function.
Mode selection is made from the application level.
- Impulse mode - it is possible to set the automatic switching off of a relay after a specific time, the so-called impulse control used for controlling gates, the function is realised by means of scenes in the Tuya application.
Possibilities of Tuya control software:
- Setting the default state of the relay after power-up to: on, off, last state
- Disabling the LED indicator of the internet connection status
- Sharing device control with others
- Scheduler - automatic start-up in weekly mode
- Timer - automatic switching off of the relay after a period of time
- Google and Alexa voice assistant integrations

When you buy you receive:
- 4 channel WiFi + RF433MHz controller with voltage-free outputs working with Tuya, Smart Life application
A5VDC power supply unit with micro USB output is required for operation, e.g. a phone charger or any other unit with a voltage of 7-32V
Radio remote control not included. For operation, the controller requires a connection to a 2.4GHz wifi network, it does not work with 5GHz networks

Adding to Tuya, Smart Life application
Once connected to the power supply, the controller confirms that it is ready for pairing by flashing the red LED, at this point we launch the Tuya application and carry out the addition of the device by clicking on the "+" button in the top right corner.
If the controller has already been paired before and you want to put it into pairing trim, hold down the "Reset" button for about 10s until the red LED starts blinking.
Adding radio remote controls:
Start the function of adding radio remotes in the Tuya app and follow the instructions on the screen.
Deleting radio remotes:
Start the function in the Tuya app and follow the instructions on the screen.
